Two delays in one: DDLY analyzes your audio based on an adjustable threshold to determine what to send to the top delay and what to send to the bottom delay. Adjust the Intensity to affect how strongly the signal is split between the two—great for a punchy delay on the harder, transient crack of your drums and a shuffling delay on the main beat elements.

iZotope products support three methods of authorization. The method that will be best for you is based on the machine(s) on which you want to install your iZotope products.

If your computer is connected to the internet: The most commonly-used authorization method is Online Authorization, where you can use your serial number to directly authorize a product, after product installation on your machine.

If your computer is not connected to the internet: For offline machines, we offer a Challenge/Response authorization method. For this process, a challenge code is provided by the software on the desired machine after you perform the installation. This challenge code must then be submitted to our website via another web-connected device. A response code or file is then provided that you can use to authorize the offline machine.

If you use an iLok: Our products also support iLok authorization for offline machines, or for users who are using iZotope products on-the-go on a number of different machines.
